Times where being possessed causes the vessel to transform in Fan Works.
Crossovers
- In Avengers: Infinite Wars, after Karness Muur takes one of Kaecilius’s acolytes as his new host, Muur is able to reshape the man’s body to resemble his original one.
- Jaune Arc, Lord of Hunger: When Darth Nihilus takes over Jaune's body, he morphs it into a shadowy mass and changes his clothes into the hooded Black Cloak Nihilus wore in Knights of the Old Republic II: The Sith Lords.
- Monkey and Butterfly: Referenced; in order to explain Ace's abilities to Moon without explaining about the Devil Fruits, they tell her that he was possessed by a fire spirit that permanently altered his body.
- In A Colder War, Steve, teen Tony, and an astronaut go up into space to rescue a lost space shuttle and meet one of the crew, Shipley, who is eventually revealed to have been possessed by the essence of Johann Schmidt, the Red Skull. Once his identity is exposed, Schmidt reveals that his face has already assumed its original red-skulled appearance and he was just wearing Shipley’s original face as a mask. Seeing the astronaut’s transformation, Steve reflects that he hopes Shipley is dead because he can’t imagine the man would want his body back after it was changed like that even if he could find a way to ‘exorcise’ Schmidt’s consciousness.
My Little Pony: Friendship Is Magic
- The Power of the Equinox: The Entity already transforms Twilight Sparkle into Dimmed Star when it takes root in her body. However, it's still a far cry from fully controlling her. When it does manage to drive her into a rampage in the sixth chapter, she grows claws on her hooves, her Black Eyes of Crazy turn red, and a third red eye grows below her horn, reflecting the appearance of the Entity that has three triangularly formed red eyes.
- In Persona: Spirits in Pixels
and Persona: World and Judgement, the characters' Shadows, now representing their desires to be reunited with departed loved ones (or in Aigis' case, to go back to being an emotionless machine), don't simply go One-Winged Angel upon their original's rejection this time around—they possess the original and then go One-Winged Angel. The Shadow of Yosuke Hanamura implies that if the possessed original's teammates aren't careful with their attacks, the original will die along with the Shadow.
- In Star Wars Paranormalities Trilogy, this is a common side-effect of Forceless possession. Played for horror in that, unfortunately for the hosts, they are consciously aware of both the possession and the transformation.
